TRACHYPHL(EOSOMA. 275 



The following species cannot be placed : — 



249. Peritelus imbricatis, Afots. 



Peritelus imbricatis, Motschulsky, Bull. Soc. Imp. Nat. Mosc. xx\\x, 

 pt. 1, 1866, p. 430. 



" Of the same shape as Peril, necessarius, but smaller. Elon- 

 gato-subovate, convex, black, with dense silky pubescence, the 

 forehead with a median impressed longitudinal line ; thorax with 

 three faint stripes ; elytra oblong, deeply punctato-striate, the 

 intervals pilose, with imbricated grey spots, the suture and sides 

 paler." 



Length, 3 mm. ; bi'eadth, 2 mm. 



Ceylon: Colombo. 



It is impossible to identify the species from this description, 

 and all that can be said is that it is highly improbable that it will 

 prove to be really a Peritelus ; it is more likely to be a Ptochus. 



Group IV. TRACHYPHLCEIDES. 



This vvidelv distributed group contains but few genera and 

 species, but this is probably due to the fact that they have been 

 neglected by collectors. The species are purely terrestrial in 

 their habits, and are all of small size and obscurely coloured, being 

 frequently covered with an earthy incrustation. 



Key to the Genera.

apex ; scrobe terminating in front 

 of the eye ; femora with a small

Genus TRACHYPHLffiOSOMA. 



Ti-achypklocosomn, Wollaston, Ann. Mag. Nat. Hist. (4) iv, 1869, 



p. 414. 

 Trnchyphlceops, Roeloffs, Ann. Soc. Ent. Belg. xvi, 1873, p. 165. — 



Type, T. roeloffsi, Sharp. 



Type, TrachyjjMoeosoma setosum, Well. 



Head broad, the eyes quite lateral, almost circular, small and 

 moderatelv convex. Rostrum, longer than the head and continuous 

 with it, aboiit as long as broad, not emarginate at the apex, 

 the epistorae transverse, without any limiting carina ; the scrobe 

 broadly widened behind, continued deeply right up to the eye, 

 which lies between its upper and lower margins ; mandibles rather 

 prominent and with a distinct scar ; the mentum lai'ge and cir- 

 cular, the submentum not pedunculate. Anteiince inserted near
